Two cars travel the same distance 141 m. The first car travels this distance
with a constant speed of 88 m/s. The
second car starts from rest and covers
the same distance with a constant
acceleration of 15 m/s2. In the end one
of the cars cover this distance earlier;
how many seconds later does the other
car finish? Write your answer up to one
decimal place.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
